Description

technical field [0001] The invention relates to the technical field of hydropower generation, in particular to a hydropower generation device. Background technique [0002] Hydropower generation uses rivers, lakes, etc. to flow water with potential energy from high places to low places, convert the potential energy contained in it into kinetic energy of water turbines, and then use water turbines as the driving force to drive generators to generate electricity. With the deterioration of the earth's environment and the gradual consumption of fossil energy, the focus of energy has gradually turned to electric energy. However, hydropower, as a clean, non-polluting and renewable energy, has been vigorously advocated. At present, most of the existing hydropower projects are large-scale hydropower projects, which fail to utilize the hydropower resources in many small rivers. At present, there are a small number of hydroelectric power generation devices suitable for small rivers, ...
